Gamma rays are produced when
Did you know?
Webgamma rays used for imaging are produced when a positron meets an electron inside the patient’s body, an encounter that annihilates both electron and positron and produces two gamma rays travelling in opposite directions. By mapping gamma rays that arrive at the same time the PET system is able to produce an image with high spatial resolution. WebGamma rays are basically short bursts of high-frequency EM waves emitted by the atomic nuclei. Such emission may happen when a nucleus is collided by another particle, or naturally unstable. Some elements contained in the earth spontaneously emit gamma rays: potassium-40, thorium, uranium, and the radioactive families of the last two.
WebApr 12, 2024 · Perhaps the most spectacular discovery in gamma-ray astronomy came in the late 1960s and early 1970s from a collection of defense satellites that were put into orbit for a reason completely unrelated to astronomy research. Detectors on board the Vela satellite series were designed to detect flashes of gamma rays from nuclear bomb blasts. WebGamma rays are produced during the disintegration of radioactive atomic nuclei and the decay of certain subatomic particles. Gamma rays are also produced through the process of pair annihilation, in which an electron …
